Auto-recovery Protective Device Self Reconnect Surge Voltage 63A 80A 380V 3 Phase Protector DIN Rail Mounted

Description:
Automatic over-voltage and under-voltage protector is suitable for three-phase AC 380V, 50/60Hz, rated working current 80A.
Its main feature is when the circuit has over-voltage or under-voltage problems, the product can cut off the power supply instantaneously to protect the electrical equipment from being damaged, besides,the protector can automatically turn on the power supply when the circuit voltage returns to the normal.

Features:
1. Over-voltage protection;
2. Under-voltage protection;
3. Zero line break protection;
4. Phase failure protection;
5. Phase order protection (reverse phase protection) (Opition);
6. Three-phase voltage unbalance protection;

Parameters:
Rated voltage: 3 phase 4 wires 230V/400VAC 50/60Hz;
Rated current: 63A/80A;
Power on time: 2s (System self-test);
Delay time after power-on: 40s;
Overvoltage protection value range: 280V5V;
Overvoltage recovery value range: 250V5V;
Undervoltage protection value range: 170V5V;
Undervoltage recovery value range: 185V5V;
OV and UV protection action time: 0.1s;
3 phases volt unbalance protection value: 35% default, or customised;
3 phases volt unbalance protection action time:1s;
Power off protection time: 0.1s;
Failure recovery delay time: 40s;
Faulty Signal: LED;
Grounding system: TT, TN-S, TN-C-S;
Installation:DIN rail;
Electrical isolation strength: >2000VAC, pulse: 2.5KV 1.2/50S;
Temperature: -20C+50C;
Humidity:85%;

Remark:
1. The default protection voltage imbalance rate is 35% and the recovery value is 25%.
Voltage unbalance rate = (highest phase voltage-lowest phase voltage) / highest phase voltage * 100%.
2. When the phase order of the incoming line is wrong, the green and red lights flash at the same time, and the yellow light flashes once every three seconds. Please change L1 and L2.

Package included:
1 x Voltage protector;
